Researchers estimate that Saturn's rings will only be around another few hundred million years at most.
Saturn’s iconic icy rings may not be around for future skygazers to glimpse at through their telescopes, according to new research. A new analysis of data captured by NASA’s Cassini mission, which orbited the gas giant planet between 2004 and 2017, has revealed new insights into how long the rings have been around and when they may vanish from sight. The findings have been shared in three studies published in May. Our solar system and its planets formed about 4.
Over 13 years, Cassini’s bucketlike Cosmic Dust Analyzer was able to scoop up 163 grains of dust that originated from beyond the Saturn system as they whirled around the gas giant. The rings were surprisingly “clean,” which suggested that they must not have been around long enough to accumulate an excess of cosmic dust. Meanwhile, as meteoroids infiltrate the rings, they push material within the innermost rings toward Saturn at a rapid rate.
